Asteroid Flybys in August 2025: What You Need to Know

NASA’s Center for Near-Earth Object Studies (CNEOS) continues to monitor these celestial objects, refining projections to assess any potential impact risks. For instance, asteroid 2024 YR4, initially estimated to have a 3.1% chance of impacting Earth in 2032, is now considered very unlikely to hit Earth and may instead impact the moon. This constant monitoring and refining of data underscore the importance of continued observation and research in near-Earth object studies.

Smaller asteroids, up to 30 feet across, impact Earth about once a decade, typically causing minor events like bright fireballs and sonic booms. However, larger asteroids pose a significant threat. For example, asteroid Bennu, about 1,640 feet wide, has a one-in-2,700 chance of colliding with Earth in September 2182. Such an impact could cause catastrophic damage, including earthquakes, wildfires, and severe atmospheric disruption.

How often do asteroids impact Earth?

Small asteroids (up to 30 feet) impact Earth about once a decade, while larger, more dangerous asteroids are much less frequent.

What is NASA doing to track asteroids?

NASA’s CNEOS monitors near-Earth objects, constantly refining projections to assess potential impact risks. They use both space and ground-based telescopes for these observations.

What would happen if a large asteroid hit Earth?

A large asteroid impact could cause catastrophic damage, including earthquakes, wildfires, atmospheric disruption, and significant climate change.
